Defensive publication

ABSTRACT

A PROCESS IS PROVIDED FOR PREPARING NOVEL MOLDABLE FABRICS, PARTICULARLY FABRICS COMPRISING POLYESTER STAPLE FIBERS. THESE FABRICS CAN BE HANDLED WITHOUT SIGNIFICANT DISTORTION AND CAN BE MOLDED INTO ARTICLES HAVING DEEP DRAW CONTOURS, GOOD SHAPE RETENTION OF THE MOLD, HIGH STRENGTH, AND GOOD ADHESION TO PLASTISOL COATINGS, TYPICALLY A CONVENTIONAL FABRIC COMPRISING HEAT SHRINKABLE YARN IS HEATED TO A TEMPERATURE FROM 200*F. TO 400*F. UNDER SUBSTANTIALLY ZERO TENSION FOR A PERIOD FROM ABOUT 1 SECOND TO ABOUT 30 MINUTES. THE MOLDABLE FABRICS ELONGATION BELOW 100%.

Int. Cl. D06c 29/00 US. Cl. 161-72 No Drawing. 13 Pages Specification A process is provided for preparing novel moldable fabrics, particularly fabrics comprising polyester staple fibers. These fabrics can be handled without significant distortion and can be molded into articles having deep draw contours, good shape retention of the mold, high strength, and good adhesion to plastisol coatings. Typically a conventional fabric comprising heat shrinkable yarn is heated to a temperature from about 200 F. to 400 F. under substantially zero tension for a period from about 1 second to about 30 minutes. The moldable fabrics have an area draw ratio greater than nine and handling elongation below 100%.
